Hello all, my BOSE AV3-2-1 Series II system does the same freaking thing. At higher volumes while watching DVD's when things such as explosions, car chases, screaming or yelling happens the entire system cuts out for a second and then comes right back.

Is this somethig I can fix, I have even turned my bass way down to like # 4 and it still does it. I am good with the volum level unit I hit about 68 to 70, themn it cuts out.

please help me.....

I connected my surround sound to the audio output on my samsung tv and it works fine. Of course I don't have an hdmi input on my surround sound system because its an older model, but it works great. Just got to put the surround sound to audio instead of dvd or tuner setting

1) Switch the unit off completely, using the powerswitch on the back of the bass box.
2) Switch the unit back on via de switch on the bass box.
3) The display should read BOSE 321 and than be dark.
4) Insert a CD and switch the unit on with the remote by selecting the CD/DVD mode.
5) When the sound is now OK, it means that you need to contact Bose to ask them for the latest software update for your unit. After updating your system. The problem will not reoccur.
6) in case the problem continues and at start-up using a CD, no improvement of sound is heard, the system should go into repair. Contact Bose in your country and ask for return instructions.

Unless there's some kind of pre-amp volume control on the unit it sounds like the main amp is faulty. It's clearly something common to all channels. However this could be down to that the main power amp is a single IC for both channels.

Make sure the device it is connected to has its audio properties setup correctly. If this is a cable or satellite box, most of them have a volume output level. Changing this will change overall volume.

Most amplifiers design to cut out when there is an overload, such as playing the music too loud. It helps protect the device from being damaged. If the device does it at low volume, and does it sometimes, check the wring to the speaker, something might be shorting it out intermitently.

I had my older bose 321 hooked up through vcr and sounded great. Then hooked it up through directv receiver and sounded better. then switched from direct to comcast and hooked the bose up throught the comcast hd receiver and the volume is aweful. same deal, have to crank it up high. Since the stereo built into the tv sounds so much better I disconnected the bose and am going to sell it.
